摘要
基建矿井井筒揭煤时发生煤与瓦斯突出事故问题严重,因此在揭煤前必须详细掌握揭煤区域的煤层赋存、地质构造变化、煤层瓦斯基本参数的基础数据,严格按照《防治煤与瓦斯突出规定》规定的石门揭煤两个"四位一体"要求进行设计、施工、检验,并注重揭煤新工艺技术、新型材料的引入,以实现安全、快速完成石门揭煤工作。
Capital construction mine uncovering coal seam occurrence of coal and gas outburst accident problem is serious, so in uncovering coal before must with masteruncovering coal region, geological structure, coal seam occurrence change of coal seam gas of the basic parameters of basic data, Shimen in strict accordance with the"coal and gas outburst prevention regulations"provisions of the two"coal uncoveringfour in one"requirements of the de sign, construction, inspection, and focus on theintroduction of coal uncovering new technology, new materials, to achieve safe, fast to complete the work uncovering coal in Shimen.
